摘　　要：为研究松阿扁叶蜂性信息素，于2008年5月上旬在河南省灵宝市苏村乡林场对松阿扁叶蜂进行了野外观察、诱捕实验，结果表明：松阿扁叶蜂未交配雌蜂对雄蜂有显著的引诱作用；雄蜂对未交配雌蜂的昼夜趋性反应发生在白天，有两个反应高峰，大的峰在10：00-12：00时，小的峰在14：00-16：00时；总体上，随着雌蜂日龄的增加，其诱捕的雄蜂数量逐渐下降，2日龄雌蜂诱到雄蜂数量最多，占总量24．58％，1～4日龄雌蜂的雄蜂诱捕量占总量80．73％；未交配雌蜂性信息素的正己烷粗提物引诱雄蜂效果最好。Field observation and Trapping experiments on Acantholyda posticalis were conducted in Lingbao, Henan Province, in early May 2008. The results indicated that the virgin females of Acantholyda posticalis were highly attractive to males. Males responded to virgin females from 8：00 to 19：00 in a day, with two response peaks at 10 ： 00--12：00（major） and 14：00--16：00 （ minor）, and there was no response of males between 20：00 and 7：00 of the second day. With the increase of the days after emergence of females, the catches of trap for males reduced continually. Traps baited with 2-day-old females captured most males, which consist of 24.58% of the tatal number. And 1 to 4-day-old females-baited traps caught 80.73% of all the males caught. Hexane extract of virgin females attracted most males in four kinds of extracts.
